- Create the network topology using mininet’s command line options. Do not add any controller for path setup.
- Use ovs-ofctl to create two bidirectional paths, e., the orange path between h1 and h9 and the purple path between h3 and h7. (no other pair of hosts should be able to communicate).
- After setting up the path run the following from mininet console:
- iperf h1 h9
○ iperf h3 h7 ● Then run h1 ping h9 Link bandwidth = 15Mbps
Link delay = 10ms
Tips/Resources
- Run mininet with –arp option to statically populate arp table in the hosts. A reference for example ovs-ofctl add-flow:
- https://docs.pica8.com/pages/viewpage.action?pageId=3086345 Set an idle_timeout of 0 so that flows do not expire.
